Resumo
This research evaluated the effect of the competition
in the growth of the forage grass Urochloa brizantha cv
Marandu (Brachiaria grass), in the systems of single and
mixed planting with the leguminous plant forages
Stylosanthes guianensis cv Mineirão (Stilozantes) and
Neonotonia wightii cv Common (Perennial Soy). The
experiment was carried out in a randomized block desgin
with four replications and the treatments were: Brachiaria
grass in a single system of planting; Brachiaria grass in
mixed planting with the Perennial Soy and Brachiaria grass
in mixed planting with the Stilozantes. For the growth
analysis they were harvested aleatory plants in the soil
level in each plot, and later carried to the laboratory of
Vegetable Physiology of EMBRAPA - CNPAF. The rates of
growth of the culture (TCC) of Brachiaria grass in the mixed
systems of planting were lower in relation to the single
system, and Stilozantes contributed in a more expressive
way to the reduction of this rate. Considering that maximum
TCC (kg.ha-1.dia-1) of Brachiaria grass they were obtained
84 DAE, to leaf area index (IAF) observed that the same date
corresponded to the higher IAF, and it demonstrates that
the mixed plantation didn’t affect the grass growing cycle,
but affected the values obtained for TCC and IAF. It can be
concluded that competition exists in the mixed plantation,
what interferes in the appraised parameters in different ways.
